Security of quantum key distribution
Abstract
In this work, three security models of quantum key distribution are introduced. The practical characters of the light source, the modulator and the single photon detector are analyzed, and the corresponding differences between the perfect and the practical quantum key distribution system are estimated. The details of the attacking methods and measures are de- scribed and investigated. We also focus on the device-independent class quantum key distribution protocol, which is a new important aspect of this research area.
